Today’s experimental poetry form uses amphibrachic meter. An example of a word with amphibrachic meter is “regretful”.
To keep things simple, as the meter could possibly be less commonly used, the form has only one stanza with five lines and no rhyme. Each line has three amphibrachic feet.
Here is an example poem:
Regretful expressions continue,
enduring beyond the encounter,
survey lines establish a title,
a lasting control of attention,
enduring within the remembrance.
